TextEncoder

{{APIRef("Encoding API")}} {{AvailableInWorkers}}

The TextEncoder interface takes a stream of code points as input and emits a stream of UTF-8 bytes.

Constructor

{{DOMxRef("TextEncoder.TextEncoder", "TextEncoder()")}}
- : Returns a newly constructed TextEncoder that will generate a byte stream with UTF-8 encoding.

The TextEncoder interface doesn’t inherit any properties.

{{DOMxRef("TextEncoder.encoding")}} {{ReadOnlyInline}}
- : Always returns utf-8.

The TextEncoder interface doesn’t inherit any methods.

{{DOMxRef("TextEncoder.encode()")}}
- : Takes a string as input, and returns a {{jsxref("Uint8Array")}} containing UTF-8 encoded text.
{{DOMxRef("TextEncoder.encodeInto()")}}
- : Takes a string to encode and a destination {{jsxref("Uint8Array")}} to put resulting UTF-8 encoded text into, and returns an object indicating the progress of the encoding. This is potentially more performant than the older encode() method.

const encoder = new TextEncoder();
const view = encoder.encode("€");
console.log(view); // Uint8Array(3) [226, 130, 172]
